1/8th scale race vehicles have enjoyed the benefits of gear differentials for years and now 1/8th scale tech is available for 1/10th scale racers. Thanks to companies like Team Losi, the addition of gear differentials in 1/10th scale racing has provided diff action which can handle power more efficiently and stay smoother longer between rebuilds. Once the time arrives to rebuild your TLR gear differential upgrade your seals to pure silicone. Pure silicone is slicker than the standard rubber seals while providing increased sealing properties. TSR Pro Seal Sets offer smoother, longer-lasting performance and extend the rebuild intervals keeping you on the track and out of the pits.

At TSR, we race and understand the kind of discipline and commitment needed to win at the highest level. Time in the pits is time lost on the track and our goal is to keep you out of the pits and out on the track.
